First published in 1943, Vitamins and Hormones is the longest-running serial published by Academic Press. In the early days of the Serial, the subjects of vitamins and hormones were quite distinct. The Editorial Board now reflects expertise in the field of hormone action, vitamin action, X-ray crystal structure, physiology, and enzyme mechanisms. Under the capable and qualified editorial leadership of Dr. Gerald Litwack, Vitamins and Hormones continues to publish cutting-edge reviews of interest to endocrinologists, biochemists, nutritionists, pharmacologists, cell biologists, and molecular biologists. Others interested in the structure and function of biologically active molecules like hormones and vitamins will, as always, turn to this series for comprehensive reviews by leading contributors to this and related disciplines. Vitamins are organic substances not naturally produced by the body that are necessary in trace amounts for normal physiologic and metabolic functioning. Hormones are biochemical substances produced in cells and tissues that cause a specific biological change or activity to occur elsewhere in the body. Study of both vitamins and hormones is essential to our understanding of physiology. This volume of Vitamins and Hormones,/b> contains articles on: Embryonic Stem Cells; Molecules in Blastocyst Implantation; Microarray Analysis of B Cell Stimulation; Tissue Culture Models for Studies of Hormone and Vitamin Action in Bone Cells; Transport of Leukotriene C4 and Structurally Related Conjugates; IL-1 beta Exerts a Myriad of Effects in the Brain; Leptin and Sweet Taste; Molecular, Structural and Cellular Biology of Follitropin and Follitropin Receptor; Factor VIIa/Tissue Factor-Induced Signaling; and Antiproliferative Action of Vitamin D. Vitamins and Hormones is the longest-running serial published by Academic Press. The Editorial Board reflects expertise in the fields of hormone action, vitamin action, X-ray crystal structure, physiology, and enzyme mechanisms. Every volume contains comprehensive reviews by leading contributors.
